Hello Rob,
I'm excited to see someone using the MPIX_Grequest interface. We used the MPIX_Grequest interface to implement non-blocking collective I/O, and had some bad interactions between libc's aio and the grequest callbacks. I don't know if you are running into something similar.
Maybe. Do you have a description of the problem somewhere?
The guy who did that work just left last Friday. I'll have to dig up the archives. Looks like it was a hard-to-debug segfault https://t rac. mpich.org/projects/mpich/ticket/2201
That link is 404. Not sure if temporary or permanent.
Huh. Did it word-wrap in a strange way?
It's back now. I guess Argonne hosting is inconsistent this week. Jeff
